TECHNICAL FIELD

The present disclosure relates to the field of communicationtechnologies, and in particular to a beam indication processing method,a user equipment and a network device.

BACKGROUND

Currently, radio access technologies, such as Long Term Evolution(LTE)/LTE-Advanced (LTE-A), are built on the basis of the Multiple-InputMultiple-Output (MIMO) technology plus the Orthogonal Frequency DivisionMultiplexing (OFDM) technology. The MIMO technology can improve peakrate and system spectrum utilization via spatial freedom that amulti-antenna system can achieve.

During the development of standardization, the dimension of the MIMOtechnology is continuously expanding. Specifically, the LTE Rel-8supports up to 4 layers of MIMO transmission. The Rel-9 focuses on theenhancement of Multi-User MIMO (MU-MIMO) technology. Transmission Mode(TM)-8 MU-MIMO transmission can support up to 4 Downlink (DL) datalayers. The Rel-10 extends the transmission capability of Single-UserMIMO (SU-MIMO) to up to 8 data layers.

The industry is further advancing the MIMO technology in the directionof three-dimensional and large-scale. Currently, the 3rd GenerationPartnership Project (3GPP) has completed the research project of 3Dchannel modeling, and is working on research and standardization offull-dimensional eFD-MIMO and New Radio (NR) MIMO. It is foreseeablethat in the future 5G mobile communication system, MIMO technology withlarger scale and more antenna ports will be introduced.

Large-scale massive MIMO technology uses a large-scale antenna array,which can greatly improve utilization efficiency of system frequencyband and support a larger number of access users. Therefore, the massiveMIMO technology is currently regarded as one of the most promisingphysical layer technologies in the next-generation mobile communicationsystems. In the massive MIMO technology, when employing an all-digitalarray, the maximum spatial resolution and optimal MU-MIMO performancecan be achieved. However, such structure requires a large number ofdigital-to-analog/analog-to-digital (AD/DA) converters as well as alarge number of complete RF-baseband processing channels, both ofequipment cost and baseband processing complexity will be a huge burden.In order to avoid the above implementation cost and equipmentcomplexity, digital-analog hybrid beamforming technology emerges, thatis, based on the traditional digital domain beamforming, a first-orderbeamforming is added to a RF signal at the position closed to the frontend of the antenna system. Analog beamforming enables a relativelycoarse match between the transmitted signal and the channel in arelatively simple way. The dimension of an equivalent channel formedafter the analog beamforming is smaller than the actual number ofantennas, and thus the required AD/DA converters, the number of digitalchannels and the corresponding baseband processing complexity can begreatly reduced. Residual interference of the analog beamforming may beprocessed again in the digital domain, thereby ensuring the quality ofMU-MIMO transmission. Compared to all-digital beamforming, thedigital-analog hybrid beamforming is a compromise between performanceand complexity, and has a high practical prospect in high-frequencylarge-bandwidth or large-antenna systems.

In the research of next-generation communication systems after 4G, theoperating frequency band supported by the system has been increased tomore than 6 GHz, up to about 100 GHz. The high frequency band hasrelatively abundant idle frequency resources, which can provide greaterthroughput for data transmission. At present, 3GPP has completed themodeling of high-frequency channels. Compared with low-frequency bands,the wavelength of high-frequency signals is short, more antenna elementscan be arranged on panels of the same size, and beams with betterdirectivity and narrower lobe can be formed by the beamformingtechnology. Thus, combination of large-scale antennas and high-frequencycommunication is also one of the future trends.

The beamformed analog beams are transmitted in full bandwidth, and arrayelements of each polarization direction of each high-frequency antennaarray panel can only transmit analog beams in a time divisionmultiplexing manner. Beamforming weight of the analog beams is achievedby adjusting parameters of a RF front-end phase shifter and otherdevices. At present, in the academic and industrial, the training of theanalog beam beamforming vector is usually performed by means of rollpolling, that is, array elements of each polarization direction of eachantenna panel of a terminal sequentially transmit training signals(i.e., candidate beamforming vectors) in the time-division multiplexingmanner at appointed time, so that the network side uses the trainingsignals for indication in the next beam training and transmissionservice.

The network side configures beam reporting setting information for theuser equipment (UE) through high layer signaling, including contentinformation of the beam reporting, time-domain related messages of thebeam reporting (such as periodic, aperiodic, semi-persistent), frequencygranularity of the beam reporting. The content information of the beamreporting may include identification information of at least one optimaltransmit beam selected by UE, physical layer measurement results (suchas L1-RSRP) of beams selected by UE, group information of beams selectedby UE, and the like. Based on the beam measurement and the beamreporting of the UE, the network side can select a corresponding beamfor signal transmission, and simultaneously indicate the correspondingbeam information to the UE. The UE relies on beam indication informationof the network side for signal reception.

Currently, the beam indication information of the network side isdynamically adjusted and has been agreed to be transmitted in physicallayer control channel. In the high frequency band, the beam indicationinformation may dynamically adjust the analog beams. Since the beamindication information is in the physical layer control channel, the UEneeds to decode the control channel and then selects the correspondinganalog beam according to the corresponding beam indication informationfor data and/or signal reception, thereby causing waste of resources.Further, when the interval between the physical control channel andscheduling data is small, this places high requirements on the UE'sability to process the physical layer control channel. This requiresthat the UE reasonably selects the beam indication information from thenetwork side when receiving. However, there is no conclusion in theprior art on how to reasonably select the beam indication informationfrom the network side.

FIG. 1 is a schematic diagram showing a system architecture of a beamindication processing method according to an embodiment of the presentdisclosure. As shown in FIG. 1, the system architecture provided in theembodiment of the present disclosure includes a network device 101 and auser equipment 102.

The network device 101 may be a Base Transceiver Station (BTS) in GlobalSystem of Mobile communication (GSM) or Code Division Multiple Access(CDMA), a NodeB (NB) in Wideband Code Division Multiple Access (WCDMA),an Evolutional Node B (eNB or eNodeB) in LTE, a base station in Newradio access technical (New RAT or NR), a relay station or an accesspoint, or a base station in the future 5G network, etc., which is notlimited herein.

The user equipment 102 maycommunicate with one or at least one core network via Radio AccessNetwork (RAN). The user equipment 102 may be a portable, pocket-sized,handheld, computer built-in or in-vehicle mobile device that exchangeslanguage and/or data with a wireless access network, such as PersonalCommunication Service (PCS) phone, cordless phone, Session InitiationProtocol (SIP) phone, Wireless Local Loop (WLL) station, PersonalDigital Assistant (PDA).

Referring to FIG. 2, one embodiment of the present disclosure provides abeam indication processing method, which is applied to a user equipmentand includes the following steps.

Step 201: determining beam indication information to be currently used.

When determining beam indication information to be currently used, theuser equipment may determine the beam indication information to becurrently used according to a preset rule, such as a pre-arrangement ofthe user equipment and the network side and a protocol agreement, oraccording to actual situation of the terminal. The beam indicationinformation to be currently used, which is determined by the userequipment, may be information indicated by the network device,implicitly, explicitly or in advance.

Step 202: determining a beam for reception according to the determinedbeam indication information.

When the user equipment determines the beam for reception according tothe determined beam indication information, the user equipment maydetermine the beam for reception according to a preset rule and/or anindication of the network side.

Step 203: performing receiving according to the determined beam.

After determining the beam for reception, the user equipment may performreceiving of corresponding data and/or signal according to thedetermined beam based on current actual situation.

By determining beam indication information to be currently used,determining a beam for reception according to the determined beamindication information and performing receiving according to thedetermined beam, the beam indication processing method of the embodimentof the present disclosure can enable the user equipment to reasonablyselect the beam indication information from the network side whenreceiving, thereby reducing the waste of resources caused by decodingthe beam indication information, reducing the requirement on theprocessing capability of the terminal, and ensuring the capability ofdata transmission delay and beam dynamic adjustment.

In the embodiment of the present disclosure, when determining the beamindication information to be used currently, the user equipment mayselect beam indication information that is transmitted in advance by thenetwork side. Specifically, the step 201 may include:

obtaining, by the user equipment, the beam indication information thatis transmitted in advance by the network device through Media AccessControl (MAC) control element or Downlink control information (DCI).

For example, when the beam indication information in MAC control elementor DCI is transmitted in an N-th slot, the beam indication informationmay be valid in a (N+X)-th (X is a positive integer greater than orequal to 0) slot. In other words, from the (N+X)-th slot, both of thenetwork device and the user equipment consider that the correspondingbeam information is the beam information indicated in the N-th slot.

In this way, by indicating the beam indication information in advancethrough the MAC control element or the DCI, it can reduce the waste ofresources caused by that the user equipment decodes the beam indicationinformation in real time, thereby reducing requirements for theprocessing capability of the terminal and timing.

A valid period of the beam indication information transmitted by thenetwork device in advance may be specifically:

from a moment when the beam indication information is transmitted untilthe network device notifies other beam indication information or thenetwork device closes the beam indication information; or,

K slots specified by the preset rule; or,

K slots specified by the preset rule, unless the network device notifiesother beam indication information or the network device closes the beamindication information; or,

K slots specified by the preset rule, unless other event specified bythe preset rule occurs;

where K is a positive integer greater than or equal to 1, and other beamindication information is other indication information which istransmitted by the network device and different from the beam indicationinformation.

Specifically, the beam indication information in the DCI may betransmitted together with other data scheduling information, or may beseparately transmitted on a Physical Downlink Control Channel (PDCCH).

In the embodiment of the present disclosure, the beam indicated by thebeam indication information transmitted by the network device in advancemay be one beam or at least two beams. Accordingly, the step 202 mayinclude:

when the beam indicated by the beam indication information is one beam,determining, by the user equipment, the one beam as a beam forreception; or,

when the beam indicated by the beam indication information is at leasttwo beams, determining, by the user equipment, a beam specified by thepreset rule in the at least two beams, as a beam for reception; or,determining a subsequently indicated beam of the at least two beams as abeam for reception; or, determining a beam specified by the preset rulein the at least two beams, as a beam for reception, until a subsequentindication is received.

The preset rule is, for example, a pre-arrangement, a protocol agreementof the user equipment and the network side, and the like. Thesubsequently indicated beam may be a specified beam of at least one beamselected by the network device in advance from the at least two beams.

In the embodiment of the present disclosure, before determining the beamindication information, the user equipment may report terminalcapability information and/or beam measurement report to the networkdevice, so that the network device performs corresponding scheduling andbeam indication. Specifically, before the step 201, the processingmethod may further include:

reporting, by the user equipment, the terminal capability informationand/or the beam measurement report to the network device.

The terminal capability information may include at least one of thefollowing information: terminal processing capability information andspatial related information. The terminal processing capabilityinformation mainly includes time required for the user equipment todecode the control channel, and the like. The spatial relatedinformation may include structural information of antenna and the like.The beam measurement report may include at least one of the followinginformation: which transmission beams correspond to same terminalreceive beams, and which transmission beams correspond to differentterminal receive beams.

In the embodiment of the present disclosure, the network device may useDCI carried in the PDCCH to indicate beam indication information ofphysical downlink shared channel (PDSCH) in the same slot as the PDCCH.Specifically, when the user equipment receives data and/or referencesignal of PDSCH in the current slot, the step 201 may include:

before decoding DCI of PDCCH in the current slot is completed,determining, the beam indication information that is transmitted inadvance by the network device, as the beam indication information to beused currently; or,

before decoding DCI of PDCCH in the current slot is completed,determining, beam indication information used by the user equipment inlast scheduling of another PDSCH, as the beam indication information tobe used currently; where the another PDSCH is PDSCH in a previous slotas compared with the current slot, for example, if the current slot istenth slot, the another PDSCH may be in the ninth slot, the seventh slotor the fifth slot; or,

before decoding DCI of PDCCH in the current slot is completed,determining, beam indication information used by the user equipment inlast successful reception of another PDSCH, as the beam indicationinformation to be used currently; or,

before decoding DCI of PDCCH in the current slot is completed,determining, beam indication information used by the user equipment forreceiving the PDCCH, as the beam indication information to be usedcurrently; or,

after decoding DCI of PDCCH in the current slot is completed, when theDCI includes beam indication information for indicating the currentslot, determining the beam indication information as the beam indicationinformation to be used currently; or,

after decoding DCI of PDCCH in the current slot is completed, when theDCI does not include beam indication information for indicating thecurrent slot, determining, the beam indication information that istransmitted in advance by the network device, as the beam indicationinformation to be used currently; or,

after decoding DCI of PDCCH in the current slot is completed, when theDCI does not include beam indication information for indicating thecurrent slot, determining, beam indication information used by the userequipment in last scheduling of another PDSCH, as the beam indicationinformation to be used currently; or,

after decoding DCI of PDCCH in the current slot is completed, when theDCI does not include beam indication information for indicating thecurrent slot, determining, beam indication information used by the userequipment for receiving the PDCCH, as the beam indication information tobe used currently; or,

after decoding DCI of PDCCH in the current slot is completed, when theDCI does not include beam indication information for indicating thecurrent slot, determining, beam indication information used by the userequipment for corresponding symbols before decoding the DCI iscompleted, as the beam indication information to be used currently.

In this way, by dynamically indicating the beam of the current slotthrough the DCI, data transmission delay can be reduced. Further, beforedecoding the DCI is completed, the beam indication information isdetermined according to the preset rule, so that the corresponding beamcan still be used for normal reception when the beam has not changed,thereby effectively reducing waste of resources.

It should be noted that the foregoing manners of determining the beamindication information to be currently used may be further applicable toa situation in which an interval between reception of the PDSCH in thecurrent slot and the corresponding physical layer's correct decodingacknowledgement/negative signal is less than a preset number of symbols.The preset number of symbols is usually preset.

Specifically, according to whether to correct the beam indicationinformation in the current slot, the network device may configure a timeinterval between the PDCCH in the current slot and PDSCH scheduled bythe PDCCH.

When DCI of the PDCCH does not include beam indication information forindicating the current slot, there is no time interval between the PDCCHand the PDSCH scheduled by the PDCCH; or,

when DCI of the PDCCH includes beam indication information forindicating the current slot, there is a time interval between the PDCCHand the PDSCH scheduled by the PDCCH; or,

when DCI of the PDCCH includes beam indication information forindicating the current slot and different transmission beams of thenetwork device correspond to different terminal reception beams, thereis a time interval between the PDCCH and the PDSCH scheduled by thePDCCH; or,

when DCI of the PDCCH includes beam indication information forindicating the current slot and different transmission beams of thenetwork device correspond to the same terminal reception beam, there isno time interval between the PDCCH and the PDSCH scheduled by the PDCCH.

A length of the time interval between the PDCCH and the PDSCH scheduledby the PDCCH may be determined by the network device according to PDCCHdecoding time reported by the user equipment.

Specifically, when the DCI of the PDCCH includes the beam indicationinformation for indicating the current slot, the beam indicationinformation may be valid only in the current slot, may continue to bevalid after the current slot, or may continue to be valid after thecurrent slot in case that the network device successfully receives thecorrect decoding acknowledgement signal from the physical layer.

In one embodiment of the present disclosure, before the step 203, theprocessing method may further include:

receiving, by the user equipment, high layer signaling configurationinformation transmitted by the network device, where the high layersignaling configuration information is used to implicitly indicateposition of De-modulation Reference Signal (DMRS) of the PDSCH in thecurrent slot.

Accordingly, the step 203 may include:

receiving, by the user equipment, data and/or reference signal of thePDSCH according to the determined beam and the position of the DMRS ofthe PDSCH in the current slot.

When the number of symbols corresponding to search space of the PDCCH inthe current slot is 1, and an interval between reception of the PDSCHand the corresponding physical layer's correct decodingacknowledgement/negative signal is smaller than a preset number ofsymbols, and PDCCH decoding capability of the user equipment is within 1symbol, the position of the DMRS of the PDSCH is at the third symbol inthe current slot; or,

when the number of symbols corresponding to search space of the PDCCH inthe current slot is 1, and an interval between reception of the PDSCHand the corresponding physical layer's correct decodingacknowledgement/negative signal is smaller than a preset number ofsymbols, and PDCCH decoding capability of the user equipment is within 2symbols, the position of the DMRS of the PDSCH is at the fourth symbolin the current slot; or,

when the number of symbols corresponding to search space of the PDCCH inthe current slot is 2, and an interval between reception of the PDSCHand the corresponding physical layer's correct decodingacknowledgement/negative signal is smaller than a preset number ofsymbols, the position of the DMRS of the PDSCH is at the fourth symbolin the current slot.

In the embodiment of the present disclosure, for non-slot scheduling(i.e., scheduling of control channel and scheduling data may start fromany symbol position in the slot) in the current slot, the network devicemay use DCI in PDCCH carried in a non-slot scheduling sub-slot toindicate beam indication information of PDSCH in the non-slot schedulingsub-slot. Specifically, when the user equipment receives data and/orreference signal of PDSCH in a non-slot scheduling sub-slot in thecurrent slot, the step 201 may include:

before decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, determining, the beam indication information corresponding tothe current slot, as the beam indication information to be usedcurrently, where the beam indication information corresponding to thecurrent slot may be the beam indication information that is transmittedin advance by the network device or the beam indication informationincluded in DCI of PDCCH in the current slot; or,

before decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, determining, the beam indication information used by the userequipment in last non-slot scheduling, as the beam indicationinformation to be used currently; where the last non-slot scheduling maybe in the current slot or a previous slot as compared with the currentslot; or,

before decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, determining, beam indication information used by the userequipment when the user equipment successfully schedules other PDSCH inthe last non-slot scheduling, as the beam indication information to beused currently; or,

before decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, determining, beam indication information used by the userequipment for receiving the PDCCH, as the beam indication information tobe used currently; or,

after decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, when the DCI includes beam indication information forindicating the non-slot scheduling sub-slot, determining the beamindication information as the beam indication information to be usedcurrently; or,

after decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, when the DCI does not include beam indication information forindicating the non-slot scheduling sub-slot, determining, the beamindication information corresponding to the current slot, as the beamindication information to be used currently; or,

after decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, when the DCI does not include beam indication information forindicating the non-slot scheduling sub-slot, determining, the beamindication information used by the user equipment in last non-slotscheduling, as the beam indication information to be used currently; or,

after decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, when the DCI does not include beam indication information forindicating the non-slot scheduling sub-slot, determining, beamindication information used by the user equipment for receiving thePDCCH, as the beam indication information to be used currently; or,

after decoding DCI of PDCCH in the non-slot scheduling sub-slot iscompleted, when the DCI does not include beam indication information forindicating the non-slot scheduling sub-slot, determining, beamindication information used by the user equipment for correspondingsymbols before decoding the DCI is completed, as the beam indicationinformation to be used currently.

In this way, by dynamically indicating the beam of the non-slotscheduling sub-slot through the DCI, the beam can be adjusted in realtime. Further, before decoding the DCI is completed, the beam indicationinformation is determined according to the preset rule, so that thecorresponding beam can still be used for normal reception when the beamhas not changed, thereby effectively reducing waste of resources.

Specifically, according to whether to correct the beam indicationinformation in the non-slot scheduling sub-slot, the network device mayconfigure a time interval between the PDCCH in the non-slot schedulingsub-slot and PDSCH scheduled by the PDCCH.

When DCI of the PDCCH does not include beam indication information forindicating the non-slot scheduling sub-slot, there is no time intervalbetween the PDCCH and the PDSCH scheduled by the PDCCH; or,

when DCI of the PDCCH includes beam indication information forindicating the non-slot scheduling sub-slot, there is a time intervalbetween the PDCCH and the PDSCH scheduled by the PDCCH; or,

when DCI of the PDCCH includes beam indication information forindicating the non-slot scheduling sub-slot and different transmissionbeams of the network device correspond to different terminal receptionbeams, there is a time interval between the PDCCH and the PDSCHscheduled by the PDCCH; or,

when DCI of the PDCCH includes beam indication information forindicating the non-slot scheduling sub-slot and different transmissionbeams of the network device correspond to the same terminal receptionbeam, there is no time interval between the PDCCH and the PDSCHscheduled by the PDCCH.

A length of the time interval between the PDCCH and the PDSCH scheduledby the PDCCH may be determined by the network device according to PDCCHdecoding time reported by the user equipment.

Specifically, when the DCI of the PDCCH includes the beam indicationinformation for indicating the non-slot scheduling sub-slot, the beamindication information may be valid only in the non-slot schedulingsub-slot, may continue to be valid after the non-slot schedulingsub-slot, or may continue to be valid after the non-slot schedulingsub-slot in case that the network device successfully receives thecorrect decoding acknowledgement signal from the physical layer.

Hereinafter, processes of determining beam indication informationaccording to a first example and a second example of the presentdisclosure will be described with reference to FIG. 3 and FIG. 4,respectively.

First Example

Referring to FIG. 3, in the first example, there are 14 slots, which areslot N, slot (N+1), slot (N+2), slot (N+3), . . . , slot (N+12) and slot(N+13), respectively. For these slots, a beam validation process mayinclude:

(1) in the slot (N+1), the network side transmits in advance beamindication information to UE1 through the MAC control element toactivate multiple beams;

(2) starting from slot (N+3), according to the preset rule, beam 1 ofthe activated beams becomes valid, and UE1 receives data based on thebeam 1 in the slot (N+3), slot (N+4), slot (N+5) and slot (N+6);

(3) in the slot (N+7), DCI of PDCCH in symbol 0 includes new beamindication information which can trigger beam 2, and the beam 2 maybecome valid after the network side receives correct decodingacknowledgement signal from the physical layer; at symbol 1, since theUE1 cannot fully decode the PDCCH in symbol 0 before reception, the UE1still receives data according to beam indication information that isvalid in the slot (N+6), i.e., the beam 1; at symbols 2-10, the UE1 candecode the PDCCH before reception, the UE1 receives data according tonew beam indication information, i.e., the beam 2; after the data iscorrectly received, the UE1 feeds back correct reception ACK informationon symbol 13; since the network side learns in advance that the UE1cannot correctly decode the PDCCH before reception at the symbol 1, thenetwork side schedules not transmitting data at the symbol 1, and mayuse scheduling information to notify the UE1 of indication informationindicating that the network side does not transmit data at the symbol 1;after the UE1 learns the indication information, the UE1 discards datareceived at the symbol 1;

(4) after the network side receives the ACK information, the new beamindication information, i.e., the beam 2, becomes valid from the slot(N+8).

In this way, by indicating the beam indication information in advancethrough the MAC control element, it can reduce the waste of resourcesand reduce requirements for the processing capability of the terminaland timing. Meanwhile, the MAC control element activates multiple beams,and DCI is dynamically selected therefrom, thereby reducing overhead ofdynamic notification. Meanwhile, before decoding the DCI is completed,the UE determines the beam indication information according to thepreset rule, and can still use the corresponding beam for normalreception when the beam has not changed, thereby effectively reducingwaste of resources.

Second Example

Referring to FIG. 4, in the second example, there are 14 slots, whichare slot N, slot (N+1), slot (N+2), slot (N+3), . . . , slot (N+12) andslot (N+13), respectively. For these slots, a beam validation processmay include:

(1) in the slot (N+1), the network side transmits in advance beamindication information to UE2 through the MAC control element toactivate multiple beams;

(2) starting from slot (N+3), according to the preset rule, beam 3 ofthe activated beams becomes valid, and UE2 receives data based on thebeam 3 in the slot (N+3), slot (N+4), slot (N+5) and slot (N+6);

(3) in the slot (N+7), non-slot scheduling occurs at the same time asnormal scheduling, that is, from symbol 7 and symbol 9, the symbol 7 isa control symbol of the non-slot scheduling, and DCI of PDCCH in thesymbol 7 includes new beam indication information for indicatingnon-slot scheduling sub-slot, and the new beam indication informationcan trigger beam 4; at symbol 8, since the UE2 cannot fully decode thePDCCH in symbol 7 before reception, the UE2 still receives dataaccording to beam indication information that is valid in the slot(N+6), i.e., the beam 3; at symbol 9, the UE2 can decode the PDCCHbefore reception, the UE2 receives data according to new beam indicationinformation, i.e., the beam 4; at symbol 10, the UE2 still receives dataaccording to the beam which normally receives data in slot (N+7), i.e.,the beam 3;

(4) after the network side receives the ACK information, the new beamindication information, i.e., the beam 4, becomes valid from the slot(N+8).
